The options here relate to the differences between Jagirdars and Zamindars in Mughal India.

Option 1 suggests that Jagirdars were holders of land assignments in lieu of judicial and police duties, while Zamindars were holders of revenue rights without the obligation to perform any duties other than revenue collection. This is not entirely accurate. While it`s true that Jagirdars were assigned land, they were also obligated to collect taxes and in return they were allowed to keep a portion of those taxes.

Option 2 proposes that land assignments to Jagirdars were hereditary and that revenue rights of Zamindars were non-hereditary. However, this is also incorrect, as the positions and rights of both Jagirdars and Zamindars could be hereditary, depending on the situation.

Since none of these options renders an accurate distinction between Jagirdars and Zamindars during the Mughal era, option 4, "Neither 1 nor 2", is the correct answer. Both options have inaccuracies and misrepresent the roles and responsibilities of these two classes.
